Appeal from the United States District Court for the Northern District of New York 

(Mordue, J.). 

 ON CONSIDERATION WHEREOF, IT IS HEREBY ORDERED, ADJUDGED, 

and DECREED that this case is REMANDED to the district court for further proceedings 

consistent with this order. Defendant-Appellant Alvin Riddle appeals from a January 17, 2014, 

judgment of conviction entered pursuant to a guilty plea by the United States District Court for 

the Northern District of New York (Mordue, J.). Riddle pleaded guilty to failing to register as a 

sex offender in violation of the Sex Offender Registration and Notification Act (“SORNA”), 18 

U.S.C. § 2250(a). The district court sentenced Riddle to 77 months’ imprisonment. On appeal, 

Riddle challenges (1) SORNA’s validity under the Ex Post Facto Clause of the United States 

Constitution and (2) the procedural and substantive reasonableness of his sentence. We assume 

the parties’ familiarity with the relevant facts, procedural history of the case, and the issues 

presented for review. 

 We begin with Riddle’s contention that the registration requirements imposed by 

SORNA violate the Ex Post Facto Clause of the United States Constitution. See U.S. Const. art. 

I, § 9, cl. 3. This argument is foreclosed by our case law, which has held that if a defendant’s 

“travel and failure to register occurred after SORNA’s enactment and the effective date of the 

regulations indicating that SORNA applies to all sex offenders,” there can be “no ex post facto 

problem with [the defendant’s] conviction[].” United States v. Guzman, 591 F.3d 83, 94 (2d Cir. 

2010). Riddle strives to distinguish Guzman, with some force, as reaching only the question of 

“whether a defendant could be punished for failing to register when the relevant states had not 

yet implemented SORNA.” Appellant’s Br. 26 n.11. Whatever the merits of Riddle’s reading of 

Guzman, however, that reading is barred by United States v. Lott, 750 F.3d 214, 220 (2d Cir. 

2014), which interpreted Guzman as “reject[ing] claims that SORNA violates the . . . Ex Post 
 

 

3

Facto Clause.” We are bound by Lott, and therefore reject Riddle’s claim that his conviction 

violates the Ex Post Facto Clause. 

Turning to Riddle’s challenge to his 77-month sentence, we first address Riddle’s 

argument that the district court committed procedural error. A sentence is procedurally 

unreasonable if the district court committed a “significant procedural error, such as failing to 

calculate (or improperly calculating) the Guidelines range, treating the Guidelines as mandatory, 

failing to consider the [18 U.S.C.] § 3553(a) factors, selecting a sentence based on clearly 

erroneous facts, or failing to adequately explain the chosen sentence.” Gall v. United States, 552 

U.S. 38, 51 (2007). 

 Riddle contends that the district court relied on four clearly erroneous facts when 

determining Riddle’s sentence. For three of these four facts, however, the district court’s factual 

findings were properly supported by the record. First, the district court correctly found that 

Riddle had a history of failing to register as a sex offender. Riddle expressly admitted in his plea 

agreement that “[a]t no time after leaving Arkansas for North Carolina, or North Carolina for 

California, or California for New York, did [he] register or update his registration with Arkansas, 

North Carolina, California, or New York, as required by law.” J.A. 100, ¶ 5(k). Second, the 

district court did not err by concluding that Riddle “has a history of failing to appear and 

absconding from supervision.” J.A. 161-62. The Presentence Report (“PSR”) indicated that 

Riddle failed to appear in January, April, and November 2005, as well as October 2010 and 

January 2011. Riddle did not object to these statements before the district court, and has thus 

waived any challenge to the PSR’s factual finding. Moreover, Riddle concedes that he absconded 

from supervision in 2005, and that he was convicted of escaping from prison in 1978. Third, the 

district court accurately described Riddle’s history of using different names. As set forth in the 
 

 

4

PSR, Riddle has gone by multiple pseudonyms, including Dan Riddle, Billy Joe Riddle, and 

William Baker. 

 Riddle’s final factual challenge has more merit. In 1972, Riddle pleaded guilty to 

murdering an 80-year-old woman. The PSR stated that, according to contemporary newspaper 

accounts and institution records from the Florida Department of Corrections, Riddle raped the 

victim in addition to murdering her. Riddle was neither charged with nor convicted of rape. 

Riddle maintains that he struck the victim when she walked in on him unexpectedly, and that he 

then fled immediately. 

 At sentencing, the district court repeatedly referred to Riddle’s “eight felony convictions 

starting with the rape and murder of an 80-year-old woman.” J.A. 161. After the second 

reference to a rape conviction, Riddle’s counsel objected, explaining that Riddle had never been 

convicted of rape. The district court acknowledged that Riddle had never been convicted of rape, 

but thereafter referred to Riddle’s violent history as including an “alleged” rape. J.A. 167-68. 

Similarly, the district court’s written statement of reasons described Riddle’s “eight felonies 

including an alleged rape.” 

 It is not clear from the record, but the district court may have erred by continuing to rely 

on the allegations that Riddle raped the murder victim. Although the government is correct that 

the district court was entitled to rely on the conduct underlying Riddle’s murder conviction, the 

district court never made any factual findings about what that underlying conduct was. The PSR 

did not reach any conclusions about whether the rape actually occurred and instead simply 

recited (1) the allegations contained in contemporary newspaper accounts and Riddle’s prison 

records and (2) Riddle’s contradictory account. Whether Riddle raped the murder victim was 

thus a disputed factual question requiring resolution by the district court. In the absence of a 
 

 

5

factual finding that Riddle committed rape, the district court could not rely on unsupported 

allegations of rape to justify increasing Riddle’s sentence. See, e.g., United States v. Helmsley, 

941 F.2d 71, 98 (2d Cir. 1991) (“If an inaccuracy is alleged [in a PSR], the court must make a 

finding as to the controverted matter or refrain from taking that matter into account in 

sentencing.”). 

 We therefore conclude that this case should be remanded pursuant to the procedures set 

forth in United States v. Jacobson, 15 F.3d 19, 22 (2d Cir. 1994). On remand, the district court 

shall either (1) hold an evidentiary hearing to make a factual finding whether Riddle raped the 

murder victim, (2) state that its sentence did not rely on the allegations of rape, or (3) state that 

Riddle must be resentenced. Because we remand this case, we do not reach Riddle’s other 

challenges to the procedural and substantive reasonableness of his sentence. 

For the foregoing reasons, we hereby REMAND the case to the district court. Upon the 

conclusion of proceedings before the district court, either party may restore jurisdiction to this 

Court by filing with the Clerk a letter (along with a copy of the relevant order or transcript) 

advising the Clerk that jurisdiction should be restored. In the interest of judicial economy, the 

renewed appeal will be assigned to this panel.
